Abstract

Southern bacterial wilt of geranium caused by Pseudomonas solanacearum.

Abstract

The cause of wilting and death of Pelargonium in a garden in Raleigh, N. Carol. was identified as P. solanacearum. This isolate was also pathogenic on marigold, tomato and zinnia but not on tobacco. A marigold isolate reacted similarly but tobacco and tomato isolates were pathogenic on all 5 crops. This is believed to be a new host record.
